Finnish Citizenship by Descent

Finland

Last verified 2026-06-01Official source

Finland grants citizenship by descent to children born of at least one Finnish citizen parent, regardless of where the child is born. This right derives from the Nationality Act 2003 (Kansalaisuuslaki, 359/2003), which entered into force on 1 June 2003 and introduced gender-neutral transmission. Children born to a Finnish mother and a foreign father before 1 June 2003 were not automatically Finnish citizens under the old law; however, many may qualify for a citizenship declaration or restoration under transitional provisions. A critical provision that distinguishes Finnish law from most other descent-based systems is the retention rule under §34. A person who was born outside Finland and has acquired Finnish citizenship solely by descent automatically loses that citizenship on their 22nd birthday unless, before that date, they have (a) applied for retention of citizenship, (b) resided in Finland for a total of at least seven years before reaching the age of 22, or (c) are otherwise sufficiently connected to Finland as assessed by the Finnish Immigration Service (Migri). Finland permits dual citizenship as of the 2003 Act. Applications are processed by Migri (Finnish Immigration Service). Processing times vary from approximately two to twelve months depending on workload and document complexity.

Common Barriers

  • ⚠§34 automatic loss at age 22 for persons born abroad who have not lived in Finland and did not apply for retention before their 22nd birthday
  • ⚠Tracing Finnish ancestry through records held by Lutheran parish archives or the Population Register Centre (DVV)
  • ⚠Proving the Finnish parent was a citizen at the time of the applicant's birth (particularly relevant for births before the 2003 Nationality Act came into force on 1 June 2003)
  • ⚠Pre-2003 gender discrimination: before the 2003 Act, citizenship passed automatically only through the father in cases of unmarried parents
  • ⚠Documentary gaps for older generations, especially if the Finnish ancestor emigrated decades ago
  • ⚠Apostille and certified translation requirements for all foreign-language documents

Documents Needed

  • •Birth certificate of the applicant (apostilled and translated into Finnish or Swedish if issued abroad)
  • •Birth certificate of the Finnish parent establishing their Finnish citizenship
  • •Finnish parent's passport or identity card, or extract from the Finnish Population Information System (DVV)
  • •Marriage certificate (if applicable, to link surnames across generations)
  • •Applicant's current valid passport
  • •Completed application form (Finnish Immigration Service / Migri)
  • •For restoration after §34 loss: application to Migri demonstrating eligibility under §34(3) or §45 restoration provisions

Programme FAQs

Can I claim Finnish citizenship through my grandparent?
Generally no — Finnish citizenship by descent is a first-generation right. If your Finnish grandparent transmitted citizenship to your parent, your parent is Finnish; but the chain does not automatically continue to you unless your parent remained Finnish at the time of your birth.
I turned 22 without knowing about the §34 rule. Can I get Finnish citizenship back?
Yes. If you lost citizenship automatically at 22, you may apply for restoration under §45 of the Nationality Act.
